Technical Abstract

A light-emitting device including a light-emitting element and a substrate where the light-emitting element is arranged. A housing part housing the light-emitting element and having a shape that is tapered upward from the substrate and a metal frame surrounding the light-emitting element and including the side face of the housing part made into an almost mirror-polished surface are provided on the substrate.

Patent Claims
4 claims

Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A light-emitting device comprising: a light-emitting element, a substrate having a first and second generally planar surfaces, said light emitting element being mounted directly to said first surface, a metal cover mounted directly to said substrate first surface and surrounding said light-emitting element, said metal cover including a housing part for housing the light-emitting element and defining a through hole for transmitting light emitted from the light-emitting element.

2

2. The light-emitting device according to claim 1 , wherein said housing part includes a light reflecting surface surrounding the light-emitting element and extending upwardly from the substrate first surface at a predetermined angle to the substrate first surface so as to reflect light emitted from the light-emitting element at an associated angle generally toward said through hole.

3

3. The light-emitting device according to claim 1 , wherein the substrate is formed of a non-metal material and has a wiring pattern, the wiring pattern including conductive vias and wiring, the wiring being formed on the second surface of the substrate, the vias extending through the substrate from said first surface to said second surface thereof and electrically connecting the wiring to said light-emitting element.

4

4. The light-emitting device according to claim 2 , wherein the substrate is formed of a non-metal material and has a wiring pattern, the wiring pattern including conductive vias and wiring, the wiring being formed on the second surface of the substrate, the vias extending through the substrate from said first surface to said second surface thereof and electrically connecting the wiring to said light-emitting element.
